Application'filed April 1, 1916. Serial No. 88,273.

To all whom it may concern Be it known that I, Josern Aunnnsou, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of ()klahoma, have invented certain new and useful Improvements in Sasl1-Stops, of which the follmving is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in sash stops of that type permitting the raising or lowering of the ordinary window sashes but limiting the I relative opening movements thereof to enable desired ventilation of a room while precluding unauthorized persons opening the window to such an extent will enable entrance to the room from the exterior thereof.

The invention embraces improved means to the ends stated having the characteristics of simplicity, ready installation, and efliciency in operation.

-)evices embracing the features just noted may be of various forms but for the sake of illustration herein 1 will disclose but two of such forms, the details in the construction and arrangement of parts thereof being clear upon a reading of the specific description hereinafter contained in connection with the accompanying drawings forming part hereof and wherein said preferred forms or embodiments of the invention are illustrated.

In the drawings :Figure 1 is a face view of an ordinary window casing with the customary vertically sliding upper and lower sashes suitably mounted therein, and provided with my improved window stops, one form being shown at the left of the Structure and another at the right. Fig. 2 is a horizontal sectional view on the line 22,of Fig. 1. Fig. 3 is a similar view on the line 3*8 of Fig. 1. Figs. 4: and 5 are respectively vertical sections showing the stops in working position with the sash members open to the 7 limit of their movement. Figs. 6 and 7 are detail views of the implement for inserting the threaded casing of Figs. 3 and 5.

Referring more specifically to the drawings, wherein like reference characters designate the same parts in the several views. A represents a window casing or frame of any conventional or preferred type, B the lower sash member slidable vertically therein in a manner so well known as to not require special illustration here, and C the similarly vertically slidable upper sash.

D and E are metal contact or stop plates secured to the upper exposed edge of the lower sash to afford properly protected impact points for the stops now to be defined, and without any undue marring or splitting of the said top or meeting rail under harsh or unexpected uses as when an attempt might be made to break into the windew.

The side rails of the upper sash are both recessed as at F and G to constitute pockets, the pocket F being threaded interiorly as at and the pocket G being distinguished therefrom by a smooth wall or bore 9. Into the recessed or pocket portion F, I screw a metal cylinder or casing H having a com plemental exteriorly threaded surface, it being understood that where the sash is of wood, in keeping with the usual practice, the recessed portion F need not be initially threaded but the threads may be formed therein coincidently with the insertion of the casing or cylinder H. l

The outer end of the casing or cylinder H is flanged as at h to engage the face of the sash and limit the inward or inserting movement thereof under the action of a suitable screw-driver or implement J having spaced lugs j for engaging slots y" in the end of the cylinder or casing H as will be obvious.

The cylinder or casing H is interiorly threaded as indicated at K for the reception of a corresponding extcriorly threaded plug l.- adapted to be shifted longitudinally of the member H upon the rotating of said plug to withdraw into the cylinder a preferably flattened reduced or projecting part Z or to project the same forwardly outside of the member H when the projection Z will constitute a stop in position to engage the stop plate D on the companion sash.

The member H has an inwardly pr0jecting shoulder portion or flange M designed to prevent removal of the member L forwardly from the member M to prevent accidental detachment or loss of the member L. This necessitates the insertion of the plug member L from the inner or confined end of the cylinder or casing H which of course is accomplished prior to the introduction of the member H into the receiving recess or socket of the sash.

In that form of the stop member Which is designed for insertion in the smoothqvalled socket or recess G, the cylinder or casing in have provided a window stop abundantly capablev of performing its intended functions.

The operation is readily understood but it maybe added that in use, it is simply necessary to turn the plug by engaging the flattened projection or stop member Z between the thumb and fore-finger of the, op-

erator and turn the plug to withdraw it until stopped by the shoulder end, when, as pre viously observed, the stop is in position to engage either the abutting stop plate D or E as rthe case may be. The upper sash may then be: lowered until'the stop member is engaged, which will give the entire ventilating opening at the top of the Window; or the lower sash may be raised until the stop member is engaged to give all of the ventilating opening at the bottom of the Window; or half of the ventilating opening or other proportions of the openings may be provided at the top and bottom of the sashes by relatively'raising and lowering them untilthe stop'member is engaged.

hollow casing adapted to be inserted into and secured in a window member, said cas mg being interiorly threaded, open at its inner end, and having an inte rally flanged outer end overhanging the open interior thereof, and a plug of a diameter to fill the open interior of the casing to form there with a substantially solid rigid device, said plug being peripherally threaded to engage the threaded interior of the casing and having a reduced forwardly extending projecting 33ft adapted to constitutethe stop for an opposing window part and to be manipulated to adjust the plug in the casing, the

outer end of the plug adjacent the reduced projecting part being arranged to abut the flange on the casing to prevent removal of the plug save through the open inner end of the casing through whichthe plug is. inserted. r

In testimony whereof I hereunto affix my signature in the presence of two witnesses. JOSEPH ANDERSON. Witnesses:
